Title:
COMMUNICATION DEVICE AND METHOD FOR CARRIER FREQUENCY CONTROL
Document Type and Number:
WIPO Patent Application WO/2016/110933
Kind Code:
A1
Abstract:
The present invention comprises: an optical transmission device 10 comprising transmission/reception apparatuses 11-14, each of which transmits and receives optical signals on a different carrier frequency; a multiplexing unit 21 which frequency-multiplexes the optical signals input by the transmission/reception apparatuses 11-14; a preliminary transmission/reception apparatus 30 which mixes and interferes with the frequency-multiplexed signals and a local light signal of the same frequency setting as the carrier frequency to be used by a transmission/reception apparatus to be controlled and which generates and outputs a control signal for correction of the carrier frequency of the transmission/reception apparatus to be controlled; and a control unit 40 which performs control involving outputting, to the transmission/reception apparatus to be controlled, the control signal input by the preliminary transmission/reception apparatus 30.
